Nagios XI Install on RHEL 7 - Impact of systemd etc.

[awilson]

Hi. I'm preparing to start an install of Nagios XI using xi-latest.tar.gz on RHEL 7.2. I see in the post, "Nagios restart command failed" https://support.nagios.com/forum/viewto ... it=systemd the customer ran into some difficulties. The resolution was pulled into a ticket and isn't in the forum.

Is there guidance or other considerations that we should follow to installing on RHEL 7 instead of 6?

Thanks!

Hi.
I've attempted an install. I have the following dependency errors:

I installed Config::Tiny, Crypt::DES, and Parse::RecDescent using cpan. I restarted my shell so that I would pickup the new environment variables cpan added when it was installed. I still get the dependency errors for the three perl modules. Is there a way to tell the installer that the modules are there? Should I just for forward and use --skip-broken as yum suggests? RHEL 7 uses python 2.7.5. The installed perl is v5.16.3. Any thoughts?

Thanks!

What OS installation did you perform? Was it a minimal or a full GUI, or something in between? Any proxies in use, or alternate repos?

[awilson]

We requested minimal. A server team has to build them for us. //smile

I just found Installing the post "Nagios XI on RedHat Error," https://support.nagios.com/forum/viewto ... 89#p149418. I see that this dev system is not configured to use the subscriptions. I'll have that resolved and report back.

Thanks!

Sounds good, this thread will remain open in the meantime.

[awilson]

Thanks. We'll probably not get that done until Monday. On the cpan vs yum install question, is there something we should do so that installing perl modules via cpan meets a dependency check?

Do you mean installing a Perl module in CPAN in such a way that yum sees it as installed? If so:

Looks like a "no", at least not easily or in a way I know of. Sometimes CPAN is unavoidable, but for all the basic things that XI needs to run, I think YUM handles the dependencies without issue.
